Why are sex linked traits expressed more frequently in males than in females?

Its called sexual dimorphism and is common in the entirety of the plant and animal kingdoms. It is simply 'just the way a particular species gets the job done'. When a species found a method that worked natural selection reinforced it.
Many people have found cause to 'take exception' to the way things are, citing justice and fairness as reasons why such shouldn't be so, but 'the universe doesn't actually care what you believe'.

∙ 13y agoIn dominant traits, there only needs to be one copy of a particular allele to cause a disease, while in recessive traits normally there needs to be two copies to cause that disease.
In sex-linked diseases the difference comes in because women have two copies of their x chromosome, while men have one x and one y. This means that if a woman has a recessive disease on one of her x chromosomes, the other one will cover up for it and the girl will still be disease free. On the other hand, if a male has a disease on his x chromosome then he has no other copy to cover it up, so it will show.

What is a trait that is passed from parent to child on the X chromosome called?
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.
Why do you sex linked traits follow different patterns of inheritance then other traits?
Males and females have different sex chromosomes.
Why are sex-linked traits more conman in males?
Because males have XY configuration of sex chromosomes and females XX. So in xy situation even the recessive gene can express. That is why sex-linked characters in males are more common than females.
How are sex linked traits unique?
Sex chromosomes themselves are unique, because of the large differences in the X and Y chromosomes. Their loci (location of genes) do not match up and the Y chromosome is much smaller. With sex-linked (X-linked or Y-linked) traits, oftentimes the genotype only consists of one allele because no form of the gene exists on the other chromosome. For this reason, males are more prone to these genetic diseases. One copy of a recessive disease-causing gene is enough to be expressed. In females, there is a chance that the other copy is dominant and not disease-causing.
When are sex link traits due to occur?
Traits caused by proteins coded for on the sex (X and/or Y) chromosomes.
Do males or females often suffer from bad sex-linked traits?
Often is certainly the wrong word. Such 'bad sex-linked traits' are considered rare.
How x linked traits affect the inheritance of sex linked traits?
Females have 2 X chromosomes so the X-linked genes follow the same rules of dominance & recessivity as the genes on the autosomes.
What is a trait that is passed from parent to child on the X chromosome called?
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.
Why do you sex linked traits follow different patterns of inheritance then other traits?
Males and females have different sex chromosomes.
Why are males more likely than females to have a sex linked traits that are recessive?
Because they olny have one X chromosome.
Why do sex-linked trait follow different pattern of inheritance than other traits?
males and females have different sex chromosomes

What is a is a sex-linked trait?
If a gene is found on the X chromosome ( and, less commomly on the Y chromosome), it is said to be a sex-linked trait. Because the gene controlling the trait is located on the sex chromosome, sex linkage is linked to the gender of the individual. Usually such genes are found on the X chromosome. The Y chromosome is thus missing such genes (See Diagram above.). The result is that females will have two copies of the sex-linked gene while males will only have one copy of this gene. If the gene is recessive, then males only need one such recessive gene to have a sex-linked trait rather than the customary two recessive genes for traits that are not sex-linked. This is why males exhibit some traits more frequently than females.

Sex-linked traits A.Can be carried on the Y chromosome B. Affect males and females equally C. Can be carried on chromosome 20 D.A and B E. None of the above?
It's A, sex linked traits can be carried by either X or Y chromosomes.
Who are the carriers in sex linked traits?
Carrier is basically when you dont have that disease but you have the gene to past it down to your children. i think this is the correct definition coz like my science taecher: Mr Aiden Kelly, like told me this. so yeh.
When are sex link traits due to occur?
Traits caused by proteins coded for on the sex (X and/or Y) chromosomes.
